Why can online videos load multiple high definition images faster than some websites load single images? Posted: 11 Nov 2016 03:53 PM PST For example a 1080p image on imgur may take a second or two to load, but a 1080p, 60fps video on youtube doesn't take 60 times longer to load 1 second of video, often being just as fast or faster than the individual image. submitted by /u/jrmcguire [link] [comments]

Have any new forms of math been created in recent years? Posted: 11 Nov 2016 01:13 PM PST I have to write a math paper on a significant person in the history of math. I know about all the people who have created algebra and calculus. But i would like to write about a more recent person who has contributed greatly to math submitted by /u/No-Spoilers [link] [comments]

Why is my girlfriend's jelly doing this? Posted: 11 Nov 2016 09:34 PM PST I know the title sounds awful, but it's a real thing. http://imgur.com/EI9hf8s No matter what we try, the jelly always rises to the top. After using it, she pushes all the jelly back to the bottom. Every time it goes back to the top. We thought maybe it was caused by an air pocket but when you push a knife through it, it still stays at the top. I know its nothing to be alarmed about, it's just kind of creepy. Any answers would be awesome because every breakfast gives me anxiety trying to figure out the jelly incident of 2016... submitted by /u/Commander-Fun [link] [comments]

Are there different frequencies of gravity? Posted: 11 Nov 2016 01:47 PM PST I don't know how to ask that properly, sorry. There are frequencies of light, sound, energy(right?) of all kinds. Are there higher or lower frequencies of gravity that we can't detect, and might that have any accountability as far as the dark energy/dark matter thing? submitted by /u/Fartbox_Virtuoso [link] [comments]

Are there articles/theories that go against popular physics, but has an undeniable point? Posted: 11 Nov 2016 02:15 PM PST The only one i can think of is James Webb's theory on how the "fine" constant along with lightspeed has differed through time. submitted by /u/TOMMYTHAMANN [link] [comments]

What is an expression for the flux of a conservative force field through or along the boundary of a Mobius strip? Posted: 11 Nov 2016 07:24 PM PST If a Mobius strip is constructed from a single closed loop, is there an analytic expression for the flux; through the surface enclosed by the loop, or for a path following the loop? So this would be to calculate the work done moving through a conservative force field along a path which is the outline defining a Mobius strip. Thanks submitted by /u/GodKingLordYoda [link] [comments]

Can we utilise metal pathways and boots to simulate gravity in space? Posted: 12 Nov 2016 12:07 AM PST Is it an option to do such a thing? Can it also be applied for exercise? submitted by /u/SamsungLipton [link] [comments]

Particle simulation of gas: handle collision by repulsion field (Coulomb's Law) or by elastic collisions? Posted: 11 Nov 2016 07:25 PM PST If there is a door #3, I'm all ears. I'm a CS guy, though I have a background in chemistry. I'm writing a particle simulator and am still in the early stages of particle-particle collisions. Suppose I have a bunch of particles that are close to each other and that are traveling with different velocities in different directions. Some of them will collide with each other. Further constraint: a computer simulation is done one frame at a time, not continuously. I have already started working on option (1) use Coulomb's law and fudge a "charge" value for each particle. For every particle, every other nearby particle will contribute a force on it. This seems to work well enough. But now I'm thinking about option (2) elastic collisions. Molecules in motion literally bounce off each other. For the sake of simplicity, I am assuming elastic collision. The collision detection and resolution would be very different than option (1), and it is more difficult to detect collisions because a simulation is frame by frame instead of continuous, so multiple particles right next to each other might not collide correctly, but it is doable. Which would give me the better simulation? submitted by /u/amdreallyfast [link] [comments]

How were the moons of other planets formed? Posted: 11 Nov 2016 09:13 PM PST The most common theory about our own moon is it was formed in the collision between our planet and another mars-sized planet. Did this happen similarly for the many moons on Jupiter and Saturn? And how does it work if the planet's made entirely of gas? submitted by /u/_-Dan-_ [link] [comments]

What's the difference between enthalpy and heat? Posted: 11 Nov 2016 06:01 PM PST Hi Reddit, maybe you can help a confused Ap Chem Student right now. It's my understanding that enthalpy equals m x s x ∆T and that heat equals m x s x ∆T as well. I get that these are two different things but I don't know how. Please help, thank you. submitted by /u/InfiniteMagicMaker [link] [comments]

How do they determine the mass of a blackhole? Posted: 11 Nov 2016 02:05 PM PST submitted by /u/GemEdessa [link] [comments]

Does compression cause the heat in a Ranque-Hilsch vortex tube? Posted: 11 Nov 2016 10:38 AM PST I recently learned about vortex tubes from this video, however I can't find a simple explanation for why the hot end gets hot. My brain says that the heat comes from compression heating at the reversal point with the air traveling towards the cold end expanding,thus getting cold. Is this what is really happening or is it something else? submitted by /u/EvilGeniusSkis [link] [comments]

How can water possibly put out a fire, since it is H2O (Hydrogen and Oxygen)? Posted: 11 Nov 2016 08:13 PM PST There must be a fundamental chemistry principal I'm not understanding. These are my assumptions: Water is H2O, Fire needs oxygen to burn, Hydrogen is used as fuel to blast rockets into space. It would seem to me that water and hydrogen peroxide (H2O2) should feed a fire rather than extinguishing it. submitted by /u/Raddad01flstc [link] [comments]

Does the atomic emission of an element affected by different isotopes? Posted: 11 Nov 2016 07:56 AM PST Do heavy and light isotopes of the same element have different emission lines? Is this also true for core electron transitions, ie x-ray emission? submitted by /u/stradivarius117 [link] [comments]

Youtube's 24/7 stream of "EARTH FROM SPACE" shows the thing the astronauts are on orbiting around earth, and they seem to be covering land very quickly. What is happening? Posted: 11 Nov 2016 08:17 AM PST I don't really know how to explain, but its as if they cover what seems to be a small area in a few minutes, but back on earth it would be hundreds if not thousands of kilometers. Is this an optical illusion? submitted by /u/plokmijnq [link] [comments]

How do you optimally place two or more Hot Pockets in a Microwave? Posted: 11 Nov 2016 04:30 AM PST Not joking. Given two or more Hot Pockets, what is the optimal configuration to insure they all get cooked evenly? submitted by /u/piedpipernyc [link] [comments]

How stable are USB thumbdrives for long-term storage? Posted: 11 Nov 2016 07:10 AM PST If I get a high-quality USB thumbdrive and put some files on it, will they still be there if I don't touch the drive for 5-10 years? Does the memory lose charge over time and eventually corrupt data? Should I plug it in to refresh the data every few months? submitted by /u/killerguppy101 [link] [comments]

Can we stand on both the ceiling and the floor of a ring shaped space station? Posted: 10 Nov 2016 08:47 PM PST If there were a space station in outer space where it has a ring that spins around to create gravity (like the ones in the movie The Martian or ones from the game Elite Dangerous) would it be possible to stand on both the ceiling and the floor due to the centripetal and centrifugal forces? submitted by /u/Nick_Fyurey [link] [comments]

Why is alpha decay always in the form of helium-4? Why does the particle never break apart into larger particles, like lithium? Posted: 10 Nov 2016 05:05 PM PST Is it to do with the amount of electrons on the outer shell? Because that would make sense as to why it's always helium. Just curious. submitted by /u/conalfisher [link] [comments]

How does music recognition/identification software work? Posted: 10 Nov 2016 09:03 PM PST I am curious of how music recognition apps, such as Shazam and Grooveshark, work.

Can a strong permanent magnetic induce enough current in a motherboard or cpu to destroy the components? Posted: 11 Nov 2016 07:42 AM PST Does a strong permanent magnetic such as a large rare earth magnetic have a strong enough magnetic field that moving it close to a processor would damage it? Alternatively could a large magnet near a cpu cause errors during its operation? submitted by /u/stradivarius117 [link] [comments]

How close can an object be to a black hole when orbiting it, without eventually getting sucked in? Posted: 10 Nov 2016 08:54 PM PST Assuming a black hole is a singularity, under classical mechanics, an object can get arbitrarily close to the black hole and still remain in stable orbit, provided it is traveling fast enough. What exactly breaks down at large scales? Does the necessary orbital velocity reach the speed of light past the event horizon? What would it be like to be on a planet currently orbiting near a black hole, according to special relativity? Also, does general relativity cause the orbiting object to lose momentum, in some way, from its own gravitational effects? (Forgive me, I don't know anything about general relativity) submitted by /u/dhelfr [link] [comments]

Can metabolic activity of cells be measured in the used media after the cells have been cultured? Posted: 11 Nov 2016 04:15 AM PST As far as i am aware the most common ways for testing if cells have been metabolic active is to perform tests on the actual cells themselves. Is there any noticeable or measurable changes in the media after cells have been cultured in them? submitted by /u/DeciduousAlpaca [link] [comments]

[GEO] What could cause these higher elevation mountains to be the warmest place in New Mexico? Posted: 10 Nov 2016 05:22 PM PST According to the USDA Plant Hardiness Map the warmest spots in New Mexico reach zone 9a (compare to central Florida). These are elevated areas at 6000-7200 feet above sea level--the Las Uvas and Florida mountains, respectively. The surrounding plains of southern New Mexico at 4000 feet above sea level are zones 7b and 8a (compare to Arkansas). What factors are causing these mountains to remain so much warmer than the rest of the state? If a resistance to inversion is to blame, why are those two mountainous areas the only places resistant to it? submitted by /u/thewindandrain [link] [comments]

[Physics]Does beta decay violate the law of conservation of mass and/or energy? Posted: 10 Nov 2016 02:54 PM PST A proton has a mass of "1" amu, a neutron has a mass of "1" amu, and an electron has a mass of "1/1836" amu. Using these values, beta decay would violate the law of conservation of mass. Where does the mass of the electron come from? submitted by /u/Maronti [link] [comments]

Why are some specific amino acids in a protein sequence phosphorylated and other not? Ex. Serine 10 is and Serine 20 is not? Posted: 10 Nov 2016 01:44 PM PST I am trying to research why certain amino acids (serines) are post translationally modified (glycosylated, lipidated, phosphorylated) while the serines in other same terminus are not affected at all. The same goes for glycosylation of asparagine and lipidation of cysteine. The prompt is specific to ADRB1 (adrenergic receptor beta 1). Any response is greatly appreciated! submitted by /u/JustBlazeEveryday [link] [comments]

[Mathematics] Is there a formula to how many perfect shuffles it takes for a certain amount of cards to go back to order? Posted: 10 Nov 2016 12:51 PM PST I was playing with some cards. I wanted to know how many perfect shuffles it takes for cards to go back to order. I then started with a low amount of cards and did more and more. but didn't do more than 14. A perfect shuffle is taking half the cards and then putting one behind the other if i have 4 cards- 1 2 3 4 (works best with even number of cards) i take 1 and 2 and shuffle them. 3 1 4 2 then again till it goes back to order. *number of cards, number of shuffles *2 2 *4 4 reverses order after 2 shuffles. *6 3 *8 6 reverses order after 3 shuffles. *10 10 reverses order after 5 shuffles. *12 12 reverses order after 6 shuffles. *14 4 *why does 14 cards only take 4 shuffles? submitted by /u/PenmanshipIsBest [link] [comments]

If a person studies a certain subject, will they lose their skill at other subjects they have studied? Posted: 10 Nov 2016 03:40 PM PST For example, if I focus on studying electrical engineering as a hobby for five years, then switch to studying chess for the next year, will I "lose" my skill at electrical engineering? Or will my brain retain everything I have studied in both areas? Does studying more topics as hobbies simply help your brain become more well rounded? Or do you only have a finite amount of brain power (seems likely unfortunately) and in your day to day life you must choose how to allocate your brain's limited resources? I feel like this is crucial question for all of academia in general. Thanks! submitted by /u/makhno [link] [comments]

How is this a Taylor expansion? Where does the integral come from? Posted: 10 Nov 2016 09:30 AM PST I found this in a paper. phi is some function, and phi_j is the value of phi at some point x_j. x is a 3d cartesian coordinate. D represents a derivative. I get the first bit - it's the first order taylor expansion, it's just a form of y(x+h)~hy(x)dy/dx. The second term looks vaguely like what I'd expect - it's got a second order derivative, and a (1/2) term in there. But for some reason there's an integral over a new variable s in there? It's not mentioned any time before in the paper - it's apparently assumed the reader recognises that this is part of a Taylor expansion. Any idea what's going on here? submitted by /u/Astrokiwi [link] [comments]

Can you travel faster than light relative to a moving object? Posted: 09 Nov 2016 06:10 PM PST So if two ships are moving away from each other, each going .9 the speed of light, their relative speed to each other would be 1.8 the speed of light. So obviously it's possible to go faster than the SOL relative to another object, right?. And everything in space is moving relative to everything else. So if the earth is moving in one direction at say .01 SOL (not just our orbit but solar system and galaxy are moving as well), and a ship travelled away from it at .99, we would be traveling at light speed as far as our origin is concerned, right? Then I think, space is just empty, how can it limit your speed with no reference, but it doesn't limit it with a reference like with the two moving ships. Sorry I hope I'm making sense. submitted by /u/goldenrule78 [link] [comments]

Is there a way of determining the boiling point of any(known) substance other than trying? Posted: 09 Nov 2016 02:00 PM PST The title really.

How exact does the energy of a photon need to be to excite an electron? Posted: 09 Nov 2016 05:59 PM PST A quick wikipedia search says that to excite a hydrogen electron from ground state to its first energy level, the photon's wavelength must be 121.6 nm. But 121.6...what? How precise does that wavelength have to really be, and why? submitted by /u/PhascinatingPhysics [link] [comments]

Is the color of a plasma due to a jump from only one shell to another, and not any other shells? Posted: 09 Nov 2016 02:14 PM PST In other words, can an argon plasma (purplish) show up as different colors if the electrons are excited to a "further away" shell? Everywhere I look says the colors of various gases are one color, but the presence of multiple energy levels in atoms makes me think there should be a variety of colors dependent on how much energy you are sending to the gas. submitted by /u/Zamperweenie [link] [comments]

How many Different bluetooth devices could stream music to separate earphones simultaneously in a railway carriage before running into bandwidth problems? Posted: 10 Nov 2016 05:55 AM PST Bluetooth has a range of ca. 10 m, comparable to a railway car, and it has 79 channels and a piconet structure with up to 8 nodes per net. Streaming music in an appropriately compressed packet format should have a well defined data rate, and it should be possible to estimate how many people could use a personal bluetooth connection within a possibly very crowded railway car simultaneously without performance impairments. I get myself confused between the protocols - can anyone help out, please? submitted by /u/Greebo24 [link] [comments]

Are galaxies laid out in any sort of order, or just scattered randomly? Posted: 10 Nov 2016 03:30 AM PST If you look at a small section of stars they look randomly positioned, but if you zoom out far enough they are arranged in galaxies. If we could zoom out even further would we find that galaxies are arranged in some sort of massive pattern, or are they just scattered randomly throughout the universe? submitted by /u/DrStalker [link] [comments]

What unit did Isaac Newton use for force? Posted: 09 Nov 2016 12:47 PM PST Sorry if this is the wrong sub, but this came up in my AP Physics class today. We decided that he probably didn't call them Newtons, but I can't find what he did call them. submitted by /u/booka800 [link] [comments]

Where did STD's come from? Posted: 10 Nov 2016 03:42 AM PST I've heard Evolutionary Psychologists saying that mongamy is not natural for men particularly, and to have as many sexual partners is a good survival mechanism to pass on your DNA to as many fertile women as possible. So why all the STD's, why have we not evolved to be immune to them when they prevent people from this purpose? submitted by /u/offthekirbYouTube [link] [comments]

How can a star turn into a black hole? Posted: 10 Nov 2016 12:26 AM PST I know if a star collapses, it can turn into a black hole. But how can the "normal" level of gravity of a star turn into gravity so strong that even light can't escape? As far as I know the mass of the star doesn't increase when it collapses, so why does the gravitational pull increase? I thought gravity was directly linked to the mass of an object. submitted by /u/xylvera [link] [comments]

How long do immunoglobin molecules last in the blood and are they being continuously created? Posted: 10 Nov 2016 05:52 AM PST I was discussing this with a friend - it's been a few years since our immunology class and I couldn't find the answer in a book. I know that after a person gets a hepatitis B vaccine, they develop immunity as anti-Hbs immunoglobulins. I'm guessing B cells which bind to antigens in the vaccine become plasma cells and memory cells and start to secrete those immunoglobulins. My question is - if we can find anti-Hbs immunoglobulins in the blood of vaccinated people even 10 years after they were vaccinated, are those the same anti-Hbs created immediately after vaccination or do memory lymphocytes continuously create the antibodies, and would exposure to the virus cause more memory cells to activate and create more antibodies to help with the immune response? Furthermore, since there are memory cells in the circulation, would whole blood transfusion from a vaccinated person to an unvaccinated person make them immune, or would the immune system of the unvaccinated person kill the foreign lymphocytes? submitted by /u/RogueTanuki [link] [comments]

[Geology] Is it possible to determine the concentration of CO2 in the atmosphere during a long-passed volcanic event? If so, how would it be done? Posted: 10 Nov 2016 01:54 AM PST Speaking mostly of the Siberian Traps eruption, but any long passed eruption will do. Would it be possible for us to measure precisely the amount of CO2 that would have been ejected into the atmosphere, or would it only be possible to estimate it? submitted by /u/idiotsonfire [link] [comments]

Given that time is quantised, does it follow that collisions are imperfect? Posted: 09 Nov 2016 10:19 PM PST Let me explain my question: I used to make games back in the day, and I often bumped into the following issue: The screen was redrawn 60 times per second. If you would move an object, you'd move it a certain amount of pixels every frame to give the illusion of movement. But imagine the following: The screen is updated 60 times per second One ball moves 4 pixels to the right every frame. Another ball moves 10 pixels to the left every frame. At frame 34 the two balls are right next to each-other and don't collide. The next frame the balls are updated and are now intersected 14 pixels! The only way I could solve this is to calculate the precise point where and when they collided to know how they should correctly bounce. Since I read somewhere that time is also quantised (just like the game was quantised to 60 hz), I wonder if subatomic particles experience the same behaviour where they can intersect, before a collision is triggered and if this has in-fact been tested or observed. I hope the question makes sense. submitted by /u/Rhinoid [link] [comments]

How does matter alter the expansion of the universe? Posted: 10 Nov 2016 12:28 AM PST I often hear regarding the future of the universe that it will either expand forever, come to a stop, or reverse and collapse depending on the amount of matter there is in it. I get that matter attracts matter but why does space-time care? Does not matter just inhabit space-time but is movable independently of it? submitted by /u/Guranmedg [link] [comments]

Posted: 09 Nov 2016 02:50 PM PST I was discussing cell biology with a friend yesterday, specifically how so many aspects of it are poorly understood. For example even in synthetic biology, where we strive to engineer organisms "from scratch", we're really starting with a quite complex and, it turns out, not fully-defined system (bacteria or yeast, usually). Anyway, we got to talking about the possibility of engineering living organisms truly from scratch, that is, without necessarily using nucleic acids, proteins and lipids as building blocks. Is this even possible? Are there other molecules that we could imagine would form the basis of a living organism? submitted by /u/free_heeler [link] [comments]

What's stopping a commercial jet airliner from being flown into space? Posted: 09 Nov 2016 09:36 PM PST With enough momentum in a 747, would it be possible to exit Earth's atmosphere? submitted by /u/wtfisrobin [link] [comments]

What advancements in science did Galileo make, other than revolutionizing astronomy? Posted: 09 Nov 2016 03:42 PM PST I've been reading about Galileo and I'm interested in learning more about him. However, many of the sources I have read have only acknowledged his advancements in astronomy. What else did he do for science? submitted by /u/childishchipolino [link] [comments]
